Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Canned tomatoes
Provide the main body, acidity, and tomato flavor of the bisque.
Milk
Forms the creamy liquid base that gives the bisque its smooth, rich texture.
Corn starch
Thickens the milk as it heats, giving the bisque body and a smooth consistency.
Butter
Adds fat for richer flavor and a silkier mouthfeel.
Baking soda
Neutralizes some tomato acidity, reducing sharpness and mellowing the flavor.

The step that matters

Bring the thickened milk and tomatoes together carefully. Acidic tomatoes can cause hot milk to curdle or separate. Adding the milk mixture to the tomatoes and heating briefly keeps the bisque smooth, so avoid overboiling once combined.

Swap the tomato

How well each one fits the dish's main ingredients (milk, corn, butter, pepper, sugar):

  1. Capsicumfits better
  2. Potatofits better
  3. Sweet potatofits about as well
  4. Tomatothe original

Fit is the average pairing score against milk, corn, butter, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
